Exam objective

SY0-701 3.4: Resilience and Recovery

Security+ Topic

Resilience and Recovery for Security+

This Security+ topic covers high availability design: high availability, load balancing, clustering, platform diversity, and multi-cloud systems; Site and continuity planning: hot site, warm site, cold site, geographic dispersion, and continuity of operations; Capacity and recovery testing: capacity planning for people, technology, and infrastructure plus tabletop exercise, failover, simulation, and parallel processing; Backup and power resilience: onsite backup, offsite backup, backup frequency, backup encryption, snapshots, recovery, replication, journaling, generators, and UPS.

Start first lesson

4 lessons in this topic

1

High Availability Designs

Compare load balancing, clustering, platform diversity, multi-cloud, and other high-availability strategies.

2

Site And Continuity Planning

Differentiate hot, warm, cold, geographically dispersed, and continuity-of-operations considerations.

3

Capacity And Recovery Testing

Explain capacity planning for people, technology, and infrastructure plus tabletop, failover, simulation, and parallel-processing tests.

4

Backups, Replication, And Power Resilience

Compare onsite/offsite backups, frequency, encryption, snapshots, recovery, replication, journaling, generators, and UPS use in recovery architecture.

Common mistakes to avoid

1

Learners often confuse load balancing and clustering. The correction is distribution versus coordinated service failover: load balancing spreads requests; clustering makes nodes work together as a resilient service.

2

Learners often rank hot, warm, and cold by temperature instead of readiness. The correction is readiness and recovery speed: hot is ready fastest, warm is partially ready, cold is mostly empty.

3

Learners often call every recovery test a simulation. The correction is to identify the test goal: discussion is tabletop, service transfer is failover, modeled event is simulation, and side-by-side operation is parallel processing.

4

Learners often treat snapshots, replication, and backups as interchangeable. The correction is that snapshots capture a point in time, replication keeps another copy updated, and backups are recoverable copies that should survive the failure scenario.
